Digging Up the Past.

Here's an old one. I completed this pencil sketch in 2004, I believe. At the time, this was considered a male Corythosaurus casuarius, but more recent studies have suggested that Corythosaurus and Lambeosaurus may share a single genus under Hypacrosaurus (Paul, 2010). So as it stands today, I'll refer to animal in the sketch as H. casuarius; the sex is undetermined.
Concerning the accuracy of the illustration, it's fairly good overall. The most glaring mistake are the tubercles under the belly--they should be fewer in number and placed behind the legs, though in front of the ischium. Other than that, it's far too similar to Greg Paul's style for me to do anything with it... you know, beyond posting it as a curiosity of my past.
I hope you enjoy it!

Antarctican prosauropod.

This is the final pencil-and-digital sketch completed for the July-September 2010 issue of Answers Magazine. The holotype's binomial is Glacialisaurus hammeri (Smith and Pol, 2007), but the remains are so scant, it is unknown whether or not the material deserves a novel genus. The bits discovered thus far appear most similar to the Chinese Massospondylus huenei. (M. huenei is often assigned the genera Lufengosaurus or Plateosaurus.)  

Because of the fragmentary condition of the remains, the image above is highly speculative.

Antarctican coelophysoid.

This is another pencil and digital sketch completed for the July-September 2010 issue of Answers Magazine. The animal depicted is Cryolophosaurus ellioti, a 6 m (20 ft) long dilophosaurid from Antarctica. The holotype--a partially complete subadult--is the only known specimen.
While this image is a decent representation of the animal, there are definitely some elements that I'd like to modify in the future.

Antarctican ankylosaur.

This is a pencil and digital sketch that I completed for the July-September 2010 issue of Answers Magazine. It appeared in an article by Buddy Davis titled, "Antarctica—Dinosaurs on Ice."  The image is a life restoration of the medium-sized ankylosaur, Antarctopelta oliveroi.  Fossils have only been recovered from a single, fragmentary and inarticulated specimen, so the image above contains a lot of conjecture.

Psittacosaur.

Here is an unfinished pencil-on-illustration board sketch from 2009.

.

This dinosaur is the prototypical psittacosaurid, called Psittacosaurus mongoliensis. P. mongoliensis is known from China, Mongolia, and Siberia. Fossils of P. mongoliensis are so abundant, nearly a full skeletal ontogeny is known for the species. At least one species of Psittacosaurus (and there are many) exibited a patch of long, moderately-flexible and hollow bristles along the dorsal surface of its tail.

As promised....

Here's a larger version of my B. walkeri image.

Baryonyx image.

I'll post a larger, watermarked version in the near future. If anyone has any questions regarding the piece or the animal, just let me know and I'll address it a.s.a.p.
